Surface heat treatment inoreva maitiro ekupisa-kurapa chete pamusoro pedenga resimbi castings. Kupisa kwepamusoro kurapwa kunogonawo kuwana iyo inodiwa metallographic chimiro uye michina zvinhu.
Inowanzo shandiswa pamusoro kupisa kupisa nzira ndeidzi: induction kupisa quenching, murazvo kupisa quenching, laser kupisa kurapwa, kuonana kuramba kupisa quenching, electrolyte quenching, pulse kupisa kupisa kurapwa, etc. Kuburikidza pamusoro kupisa kupisa, castings uye dzimwe simbi zvikamu anogona kuwana pamusoro layer. iyo inosangana nezvinodiwa zvekuita.
Mushure meiyo yekuomeswa kwepamusoro yawanikwa nekudziya kwepamusoro uye kudzimwa, iyo yepakati yekukanda inogona kuramba ichichengetedza iyo yekutanga microstructure uye kuita, kuitira kuti uwane yakanakisa dhizaini yekuvandudza simba rekuneta, kuvandudza kupfeka kuramba uye kuchengetedza kuomarara. Panguva imwecheteyo, kupisa kwepamusoro kurapwa kunogona kuderedza kushandiswa kwesimba uye panguva imwechete kuderedza kudzima deformation.
Induction kuomeswa inzira yekupisa kupisa iyo inoshandisa kupisa kunoitwa neiyo induction ikozvino kuburikidza neworkpiece kupisa pamusoro pekukanda, munharaunda kana yese, uyezve kuita nekukurumidza kutonhora. Misimboti yekutanga yekudziya yekudziya ndeye: electromagnetic induction, ganda maitiro uye kupisa conduction.
Hunhu hweInduction Heating Kudzima:
1) Induction quenching ine superplasticity. Iko kuomarara kwepamusoro kweiyo workpiece ndeye 2-3 HRC yakakwirira kupfuura iyo yakajairwa kudzima. Mushure mekupisa kupisa uye kudzima, iyo martensite yekukanda idiki uye ma carbides anoparadzirwa.
2) Kupokana kwekupfeka kwekukanda mushure mekudzimisa kupisa kwekudzimisa kwakakwira kupfuura kuya kwekudzima kwakajairwa.
3) Nekuti pamusoro peiyo workpiece yakanaka cryptocrystalline martensite uye kune compressive kushushikana, kuneta simba kweiyo workpiece inovandudzwa zvakanyanya.
4) Hunhu hweworkpiece hwakagadzikana uye deformation idiki.
5) Kukurumidza kupisa nekukurumidza uye kukwirira kwekushisa kwekushisa
6) Kubudirira kwepamusoro, nyore kuona kugadzirwa kwakagadzirwa
